It is well known that the number of elements has grown from four in the days of the Greeks to 103 at present, but the change in methods needed for their discovery is not so well known. Up until 1939, only 88 naturally occurring elements had been discovered. It took a dramatic modern technique (based on Ernest O.

EARLY DISCOVERIES AND SETTLEMENTS. [Illustration: BALBOA.] GEOGRAPHICAL KNOWLEDGE IN THE FIFTEENTH CENTURY.—The people of Europe had then never heard of America.

The Committee on English Research of the New England Historic Genealogical Society called attention in their last annual report to the fact that there were in England many important documents relating to the American colonies, as well as manuscript maps hitherto unknown to historical investigators. They urged upon the society the desirability of having exact copies of them made now while we have in Mr.... more...

PREFACE TO THE FIRST EDITION. (1872) It is not without hesitation that I have taken upon myself the editorship of a work left avowedly imperfect by the author, and, from its miscellaneous and discursive character, difficult of completion with due regard to editorial limitations by a less able hand.

FROM MISS MIRANDA MOPE, IN PARIS, TO MRS. ABRAHAM C. MOPE, AT BANGOR, MAINE. September 5th, 1879.
